Efficacy of Locally Delivred 1.2% Rosuvastatin Gel in Chronic Periodontitis

Rosuvastatin (RSV) is one of new synthetic, second-generation, sulfur-containing, hydrophilic statin, a highly efficient competitive inhibitors of HMG CoA Reductase having important role in reducing serum cholesterol concentrations and lowers the risk of cardiovascular disease. It has potent anti-inflammatory effects, mediated via vascular endothelium derived nitric oxide (eNO) that inhibits P selectin synthesis by endothelial cells. This protective action is evidenced by reduced levels of high-sensitivity C-Reactive Protein (hs-CRP) , a clinical marker of inflammation produced in response to proinflammatory cytokines such as interleukin-6 (IL-6), therefore it contributes to the prevention and remission of inflammatory diseases. Recently, an in-vivo study demonstrated that RSV promotes osteoblast differentiation, by regulating the expression of solute carrier (Slco1a1), which may constitute the transport system for RSV across the cell membrane in mature osteoblasts.
